Beyond Forcing Scenarios: Predicting Climate Change through Response Operators in a Coupled General Circulation Model: the piControl run

This is the 4000-yr control run with MPI-ESM-CR v. 1.2, carried out with fixed preindustrial CO2 concentrations. It provides the initial conditions for the abrupt 2% CO2 increase forcing and 1% ramp-up ensembles in the same project. Initial conditions are distance by 200 years in order to ensure reasonable decorrelation. The experiment is performed with MPI-ESM model, coarse resolution (CR: T31).
The project is aimed as a testbed for the Green’s functions computed via the 2xCO2abrupt experiment. This is a model application of the linear response theory, as described in Lembo et al. 2020 (see references).

本数据集系采用 MPI-ESM-CR v. 1.2 版本进行的 4000 年控制运行，运行过程中固定了工业前期的二氧化碳浓度。该数据集为同一项目中突然增加 2% 二氧化碳浓度和 1% 线性增长集合的初始条件提供了支持。为确保合理的去相关性，初始条件设定为距离 200 年。实验采用 MPI-ESM 模型进行，分辨率为粗分辨率（CR: T31）。该项目的目标是作为通过 2xCO2abrupt 实验计算格林函数的测试平台。这是线性响应理论在 Lembo 等人 2020 年描述中的应用，详见参考文献。
